my nikon sb-900 settings

I have my nikon SB-900. I've noticed last night that the built-in flash of my dslr is brighter (when you compare the photos side-by-side) on TTL mode compared to SB-900 also on TTL mode. Why is that? Is there something wrong wit my SB-900? Kindly help me. Many Thanks.

The Nikon forum would be a better place to post this question.

I assume you're using a Nikon DSLR? Check the i-TTL mode on the built-in flash on the camera and on the SB900. It sounds like:

1. You're using standard i-TTL mode on the built-in flash. The flash blasts off without taking into account the ambient light. The result is usually that the flash overpowers the ambient light
2. You're using i-TTL BBL mode on the SB900. The camera will try to balance the ambient light and the SB900 and do more of a fill-in effect
